Inventory
Likely issued from ARIN-controlled inventory

No transfer record matches. ARIN's statistics show it reserved on 2015-09-27 and allocated (dated 2015-09-28) on 2015-09-29. It moved from ARIN's unissued pool to an active registration dated around the report, so it appears to be newly issued by ARIN.

ARIN's statistics show it reserved on 2015-09-27 and allocated (dated 2015-09-28) on 2015-09-29. ARIN removed its own pool record for this range as part of issuing it: the same report adds 199.88.141.0-199.88.141.255. The issuance is explained on that line.

Every record in the ARIN, RIPE NCC, APNIC, LACNIC and AFRINIC transfer logs that moved any part of this IPv4 range (ARIN's from 2009, the RIPE NCC's from 2012, APNIC's from 2010, LACNIC's from 2016, AFRINIC's from 2018). A transfer between two registries is in both logs.

RDAP lookups

Not looked up. The tracker queries RDAP for changes as they're reported (on first sight, after 24 hours and after seven days); older changes aren't looked up because today's RDAP says nothing about the past.
